NAOMI CAMPBELL, 44

One of the original supermodels, Campbell began her career on the catwalk (that's her at Oscar de La Renta in 1994) and more than 20 years later, she hasn't missed a step. Just in the past few months alone, the supermodel has posed for Burberry, with fellow model Jourdan Dunn, and Agent Provocateur.

ELLE MACPHERSON, 50

After posing on the cover of Playboy and given the nickname "The Body" in 1994, Macpherson went on to grace the cover of not one, but five Sports Illustrated Swimsuit issues. And now she just doesn't need to the land a magazine cover to retain the title – she's "The Body" every day of her life!

CLAUDIA SCHIFFER, 44

HELENA CHRISTENSEN, 46

Long before Miranda Kerr, the Danish model's brunette waves and green eyes caused a stir, especially after her romp in the sand opposite Chris Isaak in his 1991 music video "Wicked Games." More than 20 years later, Christensen is proving she hasn't lost any of her sex appeal, appearing scantily clad in a photo spread for FutureClaw magazine.

CLAUDIA SCHIFFER, 44

Schiffer earned the title of blonde bombshell after appearing in Guess ads from 1989-1991 sporting a black bustier – and little more. In 2012, the beauty returned to her career-launching roots, reprising her role as a Guess girl for the brand's 30th anniversary. "Guess will always have a soft spot in my heart, and I'm excited that 23 years later we can still work together so successfully," she said.

NAOMI CAMPBELL, 44

The meteoric success of British-born Campbell has been evident since her first Vogue cover in 1989 – also the first time the magazine covered the all-important September issue with a black model. These days, in addition to still working the catwalk, Campbell also commands the small screen as a judge on Oxygen's modeling competition The Face and has a bit part in the new Fox series Empire.

KATE MOSS, 40

What little difference two decades make for Moss, whose waifish frame and seductive, black-and-white Calvin Klein campaign made her a household name in the early '90s. In 2013, she picked up right where she left off, going pants-less for Stuart Weitzman and playing up her lean physique and sultry pout.

ELLE MACPHERSON, 50

In 1994, the woman known as The Body put just that on display with a sizzling Playboy cover for which she sported only pantyhose. Fast-forward to July 2013, and Macpherson proved how her nickname held true by recreating the iconic image for Harper's Bazaar Australia.

LINDA EVANGELISTA, 49

At the height of her fame, Evangelista, a regular on high-fashion runways and photo spreads, was best known for saying she didn't get out of bed for less than $10,000. Two decades later, she still has a million-dollar face, having appeared in a 2012 ad campaign for Chanel and strutted like a pro across the stage at the 2013 CFDA Fashion Awards.

CHRISTY TURLINGTON, 46

A member of The Trinity, alongside Campbell and Evangelista, Turlington was the face you couldn't escape in early '90s Calvin Klein ads. It's a feat she repeated in 2013, when she stripped down in ads for the brand's intimates collection. "Now I feel like it's a treat again," she told Harper's Bazaar of her return to modeling, which recently included a Jason Wu campaign.

CINDY CRAWFORD, 48

That hair! Those eyes! That mole! The All-American good looks that helped Crawford became the face of everything from Pepsi to Revlon are still going strong 20 years later, as the now mother-of-two continues to turn heads in print and in person, including at the 2013 Cannes Film Festival.
